As Oriana said, level your coach manually on the LCI keypad, you'll see front to back, and side to side leveling. Once these are set, turn the LCI keypad off and push the up arrow off ten times and then the down arrow tens times. This will reset the zero point calibration. Next time you hit Auto Level, it will return to that setting.
